Add grammar tools, CMake integration & UI enhancements

Introduce a large feature set: grammar visualization and analysis webviews (grammar graph with Dagre/D3, export, minimap), Bison conflict explanation, AST skeleton generation, and an interactive Flex rule tester. Add workspace/document symbols, workspace symbol search, CodeLens (reference counts & entry badges), inlay hints, compile commands, and tasks.json initializer. Add CMake integration with diagnostics and a command to append BISON/FLEX targets (searching up to 6 dirs). Update client extension to register new commands and richer graph rendering/UX, and add multiple server-side providers. CI: make Open VSX publish conditional and pass PAT via env. Update README and CHANGELOG, add images and test fixtures, and bump related package metadata.

 All notable changes to the **Bison/Flex Language Support** extension will be documented in this file.
 
+## [1.1.0] - 2026-03-18
+
+### Added
+
+- **Document Symbols** — Outline view (`Ctrl+Shift+O`) with collapsible sections for declarations, rules, and epilogue (Bison) or definitions, rules, and user code (Flex)
+- **Workspace Symbols** — Fuzzy symbol search (`Ctrl+T`) across all open Bison and Flex files (up to 200 results)
+- **Code Lens** — "N reference(s)" above each Bison rule and Flex start condition; "⬪ entry point" badge above the start symbol
+- **Inlay Hints** — Inline type annotations for `$$`, `$1`, `$2`, etc. derived from `%type`/`%token` declarations
+- **CMake Integration**
+  - Diagnostic warning when a `.y`/`.l` file is not referenced in a nearby `BISON_TARGET`/`FLEX_TARGET`
+  - New command **Bison/Flex: Add CMake Target** — appends the correct `BISON_TARGET` or `FLEX_TARGET` snippet to `CMakeLists.txt`
+- **Compile Commands**
+  - **Bison: Compile** — runs `bison -d` on the current file and surfaces errors as VS Code diagnostics
+  - **Flex: Compile** — runs `flex` on the current file and surfaces errors as VS Code diagnostics
+- **Grammar Tools**
+  - **Bison: Show Parse Table** — renders the `.output` parse table in a side panel
+  - **Bison: Show Grammar Graph** — interactive D3.js force-directed graph; click a node to navigate to the rule; detects left/right recursion
+  - **Bison: Explain Conflict** — detailed shift/reduce conflict analysis with fix suggestions and precedence recommendations
+  - **Bison: Generate AST Skeleton** — generates a complete C++ AST with visitor pattern, forward declarations, and node classes
+  - **Flex: Test Rule** — interactive regex tester for the pattern on the current line
+- **Initialize tasks.json** — auto-generates `.vscode/tasks.json` with Bison/Flex problem matchers; auto-detects CMake and Makefile projects
+- **Yacc Legacy Hints** — inlay hints for legacy `%pure_parser`, `%union`, and `YYSTYPE` patterns pointing to modern Bison equivalents
+- **Smart Indent** — `onEnterRules` for Bison and Flex that indent correctly after rule openers and `%{`/`%}`
+
+### Changed
+
+- README updated with all new features, configuration settings, and screenshots
+- Status bar shows a "Grammar Graph" shortcut button when a Bison file is active
+
+### Configuration
+
+Three new settings:
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `bisonFlex.showInlayHints` | `true` | Show inlay hints for `$$`/`$1`/`@$` semantic values |
+| `bisonFlex.enableCodeLens` | `true` | Show Code Lens reference counts and entry-point badges |
+| `bisonFlex.enableCmakeDiagnostics` | `true` | Warn when a `.y`/`.l` file is missing from `CMakeLists.txt` |

+### Code Lens
+
+Reference counts and entry-point indicators appear above every Bison rule and Flex start condition:
+
+- **N reference(s)** — click to open Find All References at that symbol
+- **⬪ entry point** — marks the grammar's start symbol
+
+Toggle with `bisonFlex.enableCodeLens`.
+
+### Document Symbols & Workspace Search
+
+- **Outline** (`Ctrl+Shift+O`): collapsible tree of declarations, rules, and epilogue for Bison; definitions, patterns, and user code for Flex
+- **Workspace Symbols** (`Ctrl+T`): fuzzy search across all open Bison and Flex files — tokens, rules, start conditions, abbreviations

+### Inlay Hints
+
+Inline type annotations for `$$`, `$1`, `@$`, etc. resolved from `%type` and `%token` declarations. Toggle with `bisonFlex.showInlayHints`.
+
+### CMake Integration
+
+The extension detects `CMakeLists.txt` files up to 6 directories above the current file:
+
+- **Diagnostic warning** when a `.y`/`.l` file has no `BISON_TARGET`/`FLEX_TARGET` referencing it
+- **Bison/Flex: Add CMake Target** command — appends the correct CMake snippet automatically

+### Grammar Tools

+- **Bison: Show Grammar Graph** — interactive D3.js force-directed graph of the grammar; click a node to navigate to the rule; left/right recursive rules highlighted
+- **Bison: Show Parse Table** — displays the Bison `.output` parse table in a side panel
+- **Bison: Explain Conflict** — detailed shift/reduce conflict analysis with derivations and fix suggestions
+- **Bison: Generate AST Skeleton** — generates a complete C++ AST header with visitor pattern
+- **Flex: Test Rule** — interactive regex tester for the pattern on the current line
+
+### Compile Integration
+
+- **Bison: Compile** / **Flex: Compile** — run the compiler on the current file and surface errors as VS Code diagnostics
+- **Bison/Flex: Initialize tasks.json** — auto-generates `.vscode/tasks.json` with problem matchers; detects CMake and Makefile projects
